Update:
- On April 21, 2021, Regional Council passed a motion to develop another Growth Concept that could accommodate growth to the year 2051 without expanding Halton’s existing settlement area boundary. To learn more about the new Growth Concept—known as Concept 3B, please read the webpage below and provide input through our online questionnaire (external link).
- On February 17, 2021, Regional Council directed staff to revise draft Regional Official Plan Amendment (ROPA) 48 to include the southern portions of the Milton Education Village and Agerton Secondary Plan areas in the proposed Employment Area conversions for public consultation.
- While the Growth Concepts Discussion Paper was completed prior to this Council decision, its information remains relevant for the purposes of public consultation on how we plan to accommodate population and job growth in Halton to the year 2051.
- Once adopted by Regional Council, ROPA 48 will be important to the development of a Preferred Growth Concept as part of the Integrated Growth Management Strategy.
What are Growth Concepts and why are they important?
- Halton has prepared Growth Concepts for where and how Halton will grow to 2051.
- By planning for the future, we can ensure Halton remains a great place to live as our community continues to grow.
- The Growth Concepts provide varying options on how to accommodate another 482,000 people and 222,000 jobs to meet the provincial requirement of 1,100,000 people and 500,000 jobs by 2051.
- The Growth Concepts are another step towards developing a Preferred Growth Concept for the Region.

What will growth look like?
The Region’s future urban structure will include different growth areas for development. The majority of population and job growth will occur in these locations. Growth in these areas is reflected in each Growth Concept by varying rates of intensification or densification.
How will this look in your community? Consider housing as an example: low-density areas contain single or semi-detached houses, while medium-density areas feature townhouses, duplexes and triplexes. High-density mixed-use areas will generally have apartments, multiplexes or stacked townhouses.
Low-Density to High-Density Housing
How are the Growth Concepts evaluated?
The Growth Concepts are evaluated using a framework organized around four themes. Each theme contains a series of measures for evaluating the Growth Concepts. The effects of climate change have been considered in establishing the measures for all four themes.
Regional Urban System and Local Urban Structure
- Urban structure
- Employment land supply
- Healthy and complete communities
Agriculture, Environment and Climate Change
- Agricultural land base and system
- Natural heritage protection
- Climate change
Infrastructure and Financing
- Financial impact
- Efficient use of infrastructure
Growing the Economy and Moving People and Goods
- Travel by multiple means of transportation
- Transit-supportive development
- Moving goods to business, consumers, and industries
- Employment areas
Combined with feedback received through our questionnaire, Public Information Centres (PICs) and other community engagement, the Region is using this evaluation to develop a Preferred Growth Concept for the community.
All of the Growth Concepts meet the policy objectives of the Growth Plan (2019):
- 50 per cent of all new units to be built in the existing urbanized area
- 65 persons plus jobs per hectare for all new development area
All Growth Concepts vary based on:
- rate of growth or densification/intensification
- type and location of new housing units needed
- amount of new Community Area and Employment Area required for an urban expansion
What are the Growth Concepts?
The following maps show the location of the potential new Community Area and Employment Area where future population and job growth will occur as part of the urban expansion . How much land area those potential new Community Area and Employment Area will require is shown in the accompanying pie charts.
The maps also identify strategic growth areas in the existing urbanized areas where future population and job growth will occur.
The key parts of Concept 1:
- Has a moderate rate of densification
- Most new housing will be within the existing urbanized area
- Majority of new housing units will be higher density (for example, apartments and condos) (95,600 units)
- Has more ground related units (for example, single-detached, semi-detached, row/town houses) (78,300 units) than Concept 2 and 3 but less than Concept 4
- Needs more land (2630 ha) for an urban expansion than Concept 2 and 3 but less than Concept 4
- 3,430 ha of total prime agricultural area will be urbanized
The following map shows the potential locations of future urban expansion and strategic growth areas for Concept 1.

The following chart shows the total land needed for an urban expansion and how much is comprised of Community and Employment Area for Concept 3.

The chart below compares the type of housing units needed from 2021 to 2051 for Concept 3 in the existing urbanized area or new development area.

- From a densification and new development area for housing perspective, Concept 3B is identical to Concept 3.
- Needs no land for an urban expansion
- No new Community Area land is needed
- No new Employment Area land is needed
- No prime agricultural area will be urbanized
- This concept would require:
- An unprecedented shift from Employment Land Employment—or jobs in low-rise, industrial-type buildings within business parks and industrial areas—to Major Office Employment—or jobs in office buildings and/or in the office portion of mixed-used development areas; and/or
- An unprecedented degree of intensification for employment lands to accommodate forecasted growth to 2051
- Risks future jobs and businesses being located outside of the region due to insufficient employment land in Halton to 2051
The following map shows the existing Built-Up Area and Designated Greenfield Area of the Region, as Concept 3B proposes no settlement area expansion

The key parts of Concept 4:
- Has the lowest rate of existing urbanized area there will be increased densities above those originally planned within new development area (designated greenfield area) densification
- Most new housing will be within the existing urbanized area
- More new housing units will be in the new development area than Concepts 1, 2 and 4
- Majority of new housing units will be ground-related (for example, single-detached, semi-detached, row/town houses) (89,200 units)
- Has the highest number of ground-related units needed
- Needs the most land (3,300 ha) for an urban expansion
- Needs the most new Community Area and Employment Area land for an urban expansion
- 3,900 ha of total prime agricultural area will be urbanized
The following map shows the potential locations of future urban expansion and strategic growth areas for Concept 4.

Additional evaluation: Greenhouse Gas Emissions Assessment
On April 21, 2021, Regional Council passed a motion to develop a comparative assessment of the greenhouse gas emissions expected to be associated with each Growth Concept. The study methodology and findings are detailed in a supplementary Growth Concepts report, "Integrated Growth Management Strategy: Comparative Greenhouse Gas Emissions Assessment of Growth Concepts (PDF file)."
Separate evaluation: Growth Concept 3B
On April 21, 2021, Regional Council passed a motion to develop another Growth Concept that could accommodate growth to the year 2051 without expanding Halton’s existing settlement area boundary. A separate evaluation of Concept 3B, relative to the other Growth Concepts, using the Evaluation Framework on which the other four growth concepts were evaluated in detail (as described in the Growth Concepts Discussion Paper (PDF file)) resulted in the following overall findings:
- Concept 3B performs the same as Concept 3 in terms of the financial impact associated with residential development, but does not perform as well as any other Growth Concept in terms of best ensuring non-residential assessment growth through accommodating Employment Land Employment
- Concept 3B performs the same as Concept 3 from a transportation perspective
- Concept 3B performs somewhat better than Concept 3 in terms of the potential for lower water/wastewater capital costs
- Concept 3B performs best in retaining the greatest amount of agricultural land to support the agricultural system, as no encroachment on to existing agricultural land is proposed
- As for all Growth Concepts, Concept 3B does not propose any removal or encroachment into the Natural Heritage System
- Concept 3B retains the greatest potential area for aggregate extraction as no encroachment on mineral aggregate resource areas is proposed
Next steps: developing a preferred Growth Concept
The main goal of the Growth Concepts was to test and evaluate a range of choices for how and where growth should occur in Halton Region. Developing a Preferred Growth Concept should address questions and considerations related to eight key principles. The principles are:
Mineral Aggregate Extraction
Natural Heritage Systems and Healthy Watershed
Multi-Modal Transportation, Transit-Supportive Densities and Goods Movement
